Redumped the G&W Zelda melody ROM. This game uses a SM512 which is the same as the SM511 but supports more LCD segments. First time using the new dump method on this chip type 👍

Re-dumping the melody ROM for G&W Climber. The difference between the previous dump which is in MAME ant the new one is small: the length of a single note, a melody ending one empty note earlier and the length of a number of unused empty notes is all that differs.

Second game through the new SM511 melody ROM dumper: Game & Watch Boxing. Melody ROM is byte-for-byte identical to the optical readout of the same chip. Stops and durations come from the melody-end flag via TMEL, notes from timing the R pin with the CPU held in reset.

Dumping the melody ROM from G&W Super Mario Bros. using a method I have been working on. Earlier dumps could not recover tone lengths and stop bits, so completeness was not guaranteed. This one reads those out and the result matches the optical readout with 100% accuracy.

1,300 km. One bike. Your name on it. 🚴💛 I'm riding to Paris with Team Rynkeby for kids fighting serious illness. Donate 500 SEK (≈ €45 / $50) and join me on my journey with your name on my frame. Smaller donations are just as appreciated! intranet.team-rynkeby.com/my… #TeamRynkeby

I've added a bunch more pictures to the 'MAME 2025' page mamedev.emulab.it/haze/2025-… This only really scratches the surface of things that have been done, as many of the more obscure things are difficult to cover. Not everything shown is playable as it's meant to represent progress.

MAME 0.262 represents the latest research into Sega’s nearly unheard-of-in-the-west “AI Computer”, hailing from the late ’80s. Omar Cornut put a Herculean effort into tracking down info about it, which was pivotal when emulating it: smspower.org/SegaAI/Index Show him some love!

Dumping the ROM of a Mickey Mouse clone named Altair. This unit is different from the other Elektronika clones since it also has a built-in radiation dosimeter! The ROM has been modified with a "Dosimeter Mode" that shows radiation exposure :)
